One of the key components in sports injury prevention is the identification of imbalances in leg muscle strength. However, different leg muscle characteristics may occur in large playing area (field) sports and small playing area (court) sports, which should be considered in regular injury prevention assessment. This study examined the isokinetic hamstrings-to-quadriceps (H:Q) ratio and bilater...

OBJECTIVE To evaluate whether changes in muscle strength due to 32 weeks of supervised aquatic training predicted improvements on health-related quality of life (HRQOL). METHODS Thirty women with FM aged 50.8 +/- 8.7 years were randomly assigned to an experimental group (n = 15), performing 3 weekly sessions of 60 min of warm-water exercise; or to a control group (n = 15). HRQOL was evaluated...

the aim of study was to investigate and compare the concentric torque of quadriceps and hamstring muscles and timed-walking test in two groups. thus, one group of healthy subjects and one group of patients with low grade of tibiofemoral osteoarthritis (oa) were selected. concentric torque of quadriceps and hamstring were measured in both groups. besides, pain measurement, timed-walking test, ra...

Introduction Left ventricular hypertrophy (LVH) is a common compensating process in the pressure overload mechanism of aortic stenosis (AS). Aim To identify a group of patients with a LVH pattern which may alter periprocedural and 1-year outcomes after transcatheter aortic valve implantation (TAVI). Material and methods Echocardiographic examinations of 226 patients with severe AS treated w...

  Background: The aim of this study was to investigate muscle damage indicators and electromyography activities of quadriceps muscles at 25° of hip flexion in untrained healthy females after an eccentric exercise induced muscle fiber damage.   Methods : A total of 14 healthy females participated in this pre-experimental study. The subjects performed maximal eccentric quadriceps contractions at ...

Adding steel braces to reinforced concrete frames is a common way for seismic rehabilitation of these structures. Due to ease of installation and the possibility of creating openings in the braced bays, this method of rehabilitation has been more preferred than using shear walls. In this paper, three experimental specimens including a reinforced concrete frame, a reinforced concrete frame with ...

OBJECTIVES Mechanical and neuromuscular benefits arise during ballistic stretch-shortening cycle muscle activation, yet resistance training regimens are typically non-ballistic, and in contrast to ballistic movement, require a concentric deceleration phase. DESIGN Twelve healthy males performed a unilateral, six repetition maximum non-ballistic elbow flexion-extension task during; (i) rapid s...

Objective: To assess the effects of neuromuscular electrical stimulation (NMES) associated with an isokinetic training program in healthy young men and women. Methods: Twenty participants (ten men, ten women; 21±1.5 years) underwent an isokinetic training program for knee extensors of both sides (three sets of ten concentric repetitions at 30°/s) twice a week for four weeks. One limb underwent ...

Systematic assessment of muscle strength of the lower extremities throughout the annual training cycle in athletes is crucial from a performance perspective for the optimization of the training process, as well as a health perspective with regard to injury prevention. The main aim of the present study was to determine isokinetic muscle strength of the knee flexors and extensors in female handba...
